[0067] Under the action of the fan 42 in the air flow part 4, the air passing through the clothes in the washing machine is guided to the air collecting channel 17, the air enters from the air inlet 171 of the air collecting channel 17, and enters the adapter 5 through the air outlet 172, and then enters the drying duct 41 through the through hole 511 on the top wall 51 of the adapter 5. After being heated by the heater 43 in the drying duct 41, the air enters the outer drum 1 from the exhaust port 411 to dry the clothes, thereby forming a cycle.

[0068] A condensate supply device 7 is provided at the upper inner part of the housing, and the condensate supply device 7 includes a condensate pipe 721, and the condensate pipe 721 is connected to the inner part of the outer tub 1 to supply condensate to the inner part of the outer tub 1; one end of the condensate pipe 721 is connected to a water supply valve, and the other end is connected to the outer tub 1, and the water supply valve is used to control the condensate delivery. In addition, a drainage part (not shown) composed of a drainage pipe and a drainage pump is provided at the lower inner part of the housing, and the drainage part discharges the washing water used in washing and rinsing or the condensate in the drying process to the outside.

[0069] The upper portion 14 of the rear outer tube 10 is provided with a condensate inlet column 15, and the condensate inlet column 15 is close to the rear wall of the rear outer tube 10. The condensate inlet column 15 is provided with a condensate inlet channel 151, and the condensate inlet channel 151 communicates the inside and the outside of the outer tube 1 and can guide the condensate to the inner rear wall 11 of the rear outer tube 10. The condensate pipeline 721 of the condensate supply device 7 is connected to the condensate inlet column 15 of the upper portion 14 of the rear outer tube 10, so as to supply the condensate to the inner rear wall 11 of the rear outer tube 10 through the condensate inlet channel 151.

[0070] The condensate inlet column 15 is arranged at the center of the upper rear part of the outer tube 1, and the center of the upper rear part of the outer tube 1 is the highest position of the entire outer tube 1. The above arrangement can maximize the flow path length of the condensate. In addition, the condensate inlet column 15 is integrally formed with the outer tube 1.

[0071] A guide rib 8 is provided on the inner rear wall 11 of the rear outer cylinder 10 below the condensate inlet channel 151. The guide rib 8 extends from top to bottom and is curved. The guide rib 8 is divided into two parts, left and right, with the vertical center line of the rear wall of the outer cylinder 1 as the boundary, so as to extend the residence time of the condensate on the inner rear wall 11 of the outer cylinder 1 as much as possible. The guide rib 8 diverts the condensate entering from the condensate inlet column 15, which can effectively prevent the condensate from entering the outer cylinder 1 and flowing along the minimum path under the drive of its own gravity. The setting of the guide rib 8 gives the condensate a larger contact area and surface tension, so that the condensate flows along the designed guide rib 8. The longer flow path forms a larger cooling surface, so that the inner rear wall 11 of the outer cylinder 1, except for the air inlet 171 of the air collecting channel 17, becomes the cooling wall surface of the humid air. The air inlet 171 of the air collecting channel 17 is arranged on the rear wall of the outer cylinder 1 instead of the side wall, so that the humid air must bypass the rear of the drum 2 and pass through the inner rear wall 11 of the outer cylinder 1 before entering the air flow part 4, which is more conducive to the heat exchange between the humid air and the inner rear wall 11 of the outer cylinder 1 to which condensed water is applied, thereby drying the air in time to speed up the drying process and improve the drying efficiency.

[0072] The guide ribs 8 include a first guide rib 81, a second guide rib 82 and an anti-backflow rib 83. The anti-backflow rib 83 is provided at the air inlet 171 of the air collecting channel 17, and is located on the side of the air inlet 171 close to the condensed water inlet column 15; the anti-backflow rib 83 is provided along the edge of the air inlet 171, and its shape is consistent with the shape of the air inlet 171; the anti-backflow rib 83 can effectively prevent the condensed water from being sucked into the air collecting channel 17 during the drying process, causing the clothes to be wetted again.

[0073] The first guide rib 81 includes a first rib 811 and a second rib 812 connected at one end and separated at the other end. The first rib 811 and the second rib 812 extend from the connection to the two sides of the radial line where the first rib 811 and the second rib 812 are connected on the bottom wall of the outer tube, that is, they are arranged in a "human" shape. In this embodiment, the first rib 811 and the second rib 812 are located on the mid-vertical line of the bottom wall of the outer tube from the connection, and the first rib 811 and the second rib 812 extend to the left and the left road respectively. The connection between the first rib 811 and the second rib 812 corresponds to the condensate inlet channel 151 on the condensate inlet column 15 provided on the outer peripheral wall of the outer tube 1, so as to first receive the condensate introduced by the condensate inlet channel 151 and divert it. The first rib 811 and the second rib 812 extend separately from the connection to both sides, and in this embodiment, they extend to the left and right sides. The first support rib 811 is curved and extends to the lower part of the outer tube 1 to guide the condensed water to the drainage part; the second support rib 812 extends a part of its length toward the side close to the anti-backsucking rib 83 and is separated from the anti-backsucking rib 83.

[0074] The second guide rib 82 includes a third rib 821, a fourth rib 822 and a fifth rib 823; the third rib 821 and the fourth rib 822 are connected at one end and separated at the other end, and the connection between the third rib 821 and the fourth rib 822 corresponds to the connection between the first rib 811 and the second rib 812; that is, the connection between the third rib 821 and the fourth rib 822, the connection between the first rib 811 and the second rib 812 and the outlet of the condensate inlet channel 151 are located on the same straight line; that is, the connection between the third rib 821 and the fourth rib 822 is located directly below the connection between the first rib 811 and the second rib 812. The third rib 821 is consistent in shape with the first rib 811; the fourth rib 822 is consistent in shape with the second rib 812; the third rib 821 and the fourth rib 822 extend downward for a distance; the fifth rib 823 is located below the fourth rib 822; preferably, in the vertical direction, the upper end of the fifth rib 823 is at least partially overlapped with the lower end of the fourth rib 822. Optionally, the upper end of the fifth rib 823 is also at least partially overlapped with the lower end of the second rib 812 in the vertical direction, so that the fifth rib 823 can receive the condensed water guided by the second rib 812 and the fourth rib 822, thereby extending the moving path of the condensed water guided by the second rib 812 and the fourth rib 822.

[0075] The fifth rib 823 avoids the air inlet 171 and extends downward to the lower part of the outer drum 1 to guide the condensed water to the drainage part; the segmented arrangement of the fifth rib 823, the second rib 812 and the fourth rib 822 can effectively guide the flow direction of the condensed water to the drainage part on the one hand; on the other hand, it can avoid the air inlet 171 and extend the flow path of the condensed water. In horizontal projection, the lower end projection of the second guide rib 82 is located between the lower end projection of the fourth rib 822 and the projection of the condensed water inlet column 15; the water diverted by the second guide rib 82 is first received by the fourth rib 822 downward, and then guided to the fifth rib 823 through the fourth rib 822. The above-mentioned condensed water supply device 7 supplies cold water to the inner rear wall 11 of the outer drum 1. When the washing machine performs the drying process, as the condensed water supply device 7 supplies cold water, the supplied cold water flows along the inner surface of the outer drum 1. At the same time, the moist air after drying the laundry moves toward the air collecting channel 17, thereby forming condensed water on the condensation surface (inner rear wall) of the outer drum 1 through which the cold water flows. Compared with the existing structure of using a condenser pipe to generate condensed water, the structure of using the inner surface of the outer drum 1 to generate condensed water, on the one hand, fully utilizes the existing structure of the washing machine and reduces the thickness increase caused by the additional structure; on the other hand, since a larger area can be used to generate condensed water, the generation efficiency of condensed water can be improved.

[0076] In addition, the air inside the outer drum 1 flows into the drying air duct 41 as the fan 42 is driven, and moves toward the heater 43. The heater 43 heats the air moved by the fan 42 to generate hot air. The air heated by the heater 43 is supplied to the outer drum 1 through the exhaust port 411 to dry the laundry.

[0077] In this embodiment, a front temperature sensor 31 is provided at the front end of the outer drum 1 near the drying air duct 41 to detect the temperature of the heated air; a temperature limiter 32 is provided on the side wall of the drying air duct 41 corresponding to the position of the heater to limit the heating temperature; a rear temperature sensor 33 is provided on the adapter 5 to detect the air temperature in the air collecting channel 17; the setting of the above temperature sensors can effectively detect the temperature of each part to control the drying program, so as to improve the drying efficiency and drying effect, and reduce damage to clothes.

[0080] The clean water pipeline 722 is connected to the clean water inlet column 54 on the top wall 51 to introduce water from the condensation water supply device 7 into the recessed portion 16 forming the gas collecting channel 17. The water introduced into the gas collecting channel 17 through the clean water pipeline 722 flushes the gas collecting channel 17 and supplies condensation water to the rear wall of the outer cylinder.

[0081] The air collecting channel 17 is provided with a recessed portion 16 to connect the inner rear wall 11 of the outer tube 1 with the outer peripheral wall 12 of the outer tube 1. Although the recessed portion is conducive to air collection, it is also easy to accumulate fiber dandruff and the like, which may easily cause blockage of the air collecting channel 17. In this embodiment, a clean water inlet column 54 is provided on the adapter 5 to introduce condensed water into the air collecting channel 17 to flush the air collecting channel 17 to remove fiber dandruff and the like accumulated in the air collecting channel 17, thereby avoiding blockage of the air collecting channel 17 caused by long-term accumulation of dandruff, and effectively ensuring the smooth flow of the air collecting channel 17; at the same time, it also avoids the accumulation of dandruff to breed bacteria.

In this embodiment, two condensate water channels are set, which effectively increases the contact area between the condensate and the inner rear wall of the outer cylinder, thereby maximizing the condensation heat exchange effect. At the same time, the condensed water introduced through the clean water inlet channel 541 can also clean the gas collecting channel.

The water diversion plate 50 diverts the condensed water entering from the clean water inlet channel 541, can flush the gas collecting channel in multiple directions, and increase the coverage area of ​​the condensed water, on the one hand, increasing the condensation heat exchange effect; on the other hand, the water flow rate diverted by the diversion plate 50 increases, the impact force increases, and the gas collecting channel can be effectively flushed, so that the flushing effect is better, and the flushing efficiency and flushing effect are effectively improved.

The clean water inlet column 54 is located inside the adapter 5 as a nozzle docking column 543; the first screw column 55 and the second screw column 56 are respectively arranged on both sides of the nozzle docking column 543, and the first screw column 55, the nozzle docking column 543, and the second screw column 56 are collinear. A connecting plate 57 is arranged between the first screw column 55, the nozzle docking column 543, and the second screw column 56 to connect the three as a whole, effectively improving the overall strength; a second reinforcing plate 58 is arranged between the nozzle docking column 543 and the top wall 51, and the second reinforcing plate 58 connects the nozzle docking column 543 and the top wall 51 as a whole, effectively strengthening the strength of the nozzle docking column 543.

[0090] The debris filter nozzle 6 includes a fixing portion 60 and a water spraying rod 62. The fixing portion 60 is connected to the water spraying rod 62, and the fixing portion 60 is connected to the nozzle docking column 543. The debris filter nozzle 6 is downward in the vertical direction; the water spraying rod 62 is provided with a plurality of openings 63, and the openings 63 are used to spray clean water. The side of the debris filter nozzle 6 facing the air inlet 171 of the air collecting channel 17 is recorded as a first water spraying surface 621. The fixing portion 60 is provided with a bottom plate 61 at one end away from the water spraying rod 62. The bottom plate 61 is provided with a first screw hole 611 on one side of the fixing portion 60, and a second screw hole 612 on the other side; the first screw hole 611 corresponds to the first screw column 55 on the adapter 5, and the second screw hole 612 corresponds to the second screw column 56 on the adapter 5. The bottom plate 61 is fixedly connected to the first screw column 55 and the second screw column 56 by screws 59; that is, the debris filter nozzle 6 is fixedly connected to the nozzle docking column 543 by screws 59. The condensed water passing through the nozzle docking column 543 enters the water spraying rod 62 through the fixing portion 60 and is sprayed out from the opening 63 .

[0091] The opening 63 includes a first nozzle 631; the first nozzle 631 is arranged on the first water spraying surface 621 of the debris filter nozzle 6; the first nozzle 631 includes a first spray hole 6311; a plurality of the first spray holes 6311 are arranged in the middle of the first water spraying surface 621 and are distributed along the axis direction of the water spraying rod 62; the first spray hole 6311 sprays water in a direction perpendicular to the first water spraying surface 621 to clean the area of ​​the filter net 9 facing the first nozzle 631. The first water spraying surface 621 is provided with a second spray hole 6312, which is arranged at the edge of the first water spraying surface 621, and is arranged in two rows on both sides of the first spray hole 6311, and sprays water at a preset angle to fully clean the filter net 9 with a cleaning range having a wider radius. The end of the water spray rod 62 away from the fixing part 60 is provided with a third spray hole 6313, and the third spray hole 6313 is strip-shaped, which effectively ensures the water spray amount and spray range of the end of the filter nozzle 6. The above arrangement effectively guarantees the cleaning range and ensures the pressure of the water spray, so as to effectively clean the filter screen 9 and improve the cleaning efficiency; in addition, the first spray hole 6311 and the second spray hole 6312 between two adjacent rows are relatively staggered to reduce the interference of the water sprays and ensure the cleaning effect.

[0092] In addition, the number of nozzles can be increased or decreased in proportion to the area of ​​the filter screen 9. The number of nozzles, nozzle aperture, nozzle spacing, etc. can be changed in various forms, so the number of nozzles, nozzle aperture, nozzle spacing, etc. of the present invention are not limited.

[0093] Embodiment 7

[0094] The principle of this embodiment is the same as that of the sixth embodiment, and the main difference is that Figure 25-28 As shown, a second nozzle 632 is provided on the side of the top of the debris filter nozzle 6 away from the air inlet 171. The side of the debris filter nozzle 6 away from the air inlet 171 is recorded as the second water spraying surface 622; the fixing portion 60 is provided with a second nozzle 632 on the second water spraying surface 622; the second nozzle 632 faces the rear of the outer cylinder 1 to clean the wire scraps accumulated in the wind path turning area of ​​the air collecting channel 17.

The third nozzle 633 extends downward along the circumferential surface of the fixing portion 60.

[0096] The arrangement of the second nozzle 632 and the third nozzle 633 above effectively prevents accumulated lint and the like from clogging the air collecting channel 17, causing a significant decrease in air volume and a deterioration in the drying effect, until the drying process cannot be carried out; at the same time, when the rear temperature sensor 33 is arranged in the adapter 5, lint and the like are easily accumulated on the surface of the rear temperature sensor in the adapter 5, causing distortion of the temperature detected by the rear temperature sensor, thereby affecting the judgment of the drying process.

[0097] A debris filter nozzle 6 is provided at the air inlet 171 of the air collecting channel 17, which can rinse the inner rear wall 11 of the outer tub 1 and the outer rear wall 21 of the drum 2 during the washing and drying process. During the washing and drying process, the drum 2 is controlled to rotate at a certain speed, so that the water directly impacting and splashing can cover the drum 2 and the rear area of ​​the outer tub 1 to clean them.

[0098] The washing machine of the present invention has a washing function and a drying function at the same time, and effectively improves the drying efficiency, ensures the drying effect, and improves the user experience effect.

[0099] Based on the structure of the above-mentioned washing machine, this embodiment provides a method for cleaning the drum of a washing machine, wherein the drum includes an inner drum and an outer drum of the washing machine, and the outer drum and the inner drum are cleaned by controlling the water supply to the debris filter nozzle. Specifically, when the user selects a washing-drying program, a step of cleaning the drum can be performed before rinsing the laundry to remove fiber debris between the inner drum and the outer drum. This is because the fiber debris separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum when cleaning the drum can be discharged together with the rinsing water supplied for rinsing. When the user chooses to perform a drying program alone, a step of cleaning the drum is performed before drying begins to remove fiber debris between the inner drum and the outer drum; the removed hair debris can be discharged by performing a drainage action to remove the fiber debris separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0100] The following is a detailed description of the cleaning method of the cylinder:

[0101] The drum cleaning method of a washing machine includes: a drum cleaning program, which includes an interval cleaning step of controlling the opening and closing of a cleaning water valve to provide cleaning water to a debris nozzle, and a continuous cleaning step of controlling the cleaning water valve to be continuously opened after the interval cleaning step.

[0102] The cylinder cleaning procedure is as follows: the cleaning water valve is controlled to be opened and closed intermittently for 1 to 2 seconds respectively. After the accumulated time is 16 to 32 seconds, the cleaning water valve is opened and kept for 5 to 20 seconds before being closed. This cylinder cleaning procedure can be cycled 2 or 3 times.

[0103] Furthermore, while performing the interval cleaning step, the inner drum is controlled to rotate forward and reversely, and the fan is started to use the suction force of the fan to clean the drying duct. After the interval cleaning step is completed, the fan is controlled to continue to run for a predetermined time, and the heater is turned on to heat and evaporate the remaining moisture in the drying duct.

[0104] like Fig.29 As shown, the specific contents of the barrel cleaning procedure are as follows:

[0105] When the user selects the washing-drying program, the drum cleaning program is executed before the rinsing process begins. The cleaning water valve is opened and closed intermittently, so that the cleaning water is intermittently supplied to the cleaning water inlet column, and the cleaning water is sprayed between the inner drum and the outer drum through the debris nozzle. The cleaning water valve is intermittently supplied for a certain period of time, and then the cleaning water valve is continuously opened for continuous cleaning for a certain period of time.

[0106] Here, the reason why the washing water is intermittently supplied is that when the pressure of the supplied washing water is low, the spray pressure of the washing water can be temporarily increased in the case of intermittent supply of the washing water compared to the case of continuous supply of the washing water. That is, by closing the washing water valve, the pressure of the washing water controlled by the washing water valve can be temporarily increased, and as the washing water with increased pressure is intermittently supplied, the washing water supplied from the condensed water supply device is sprayed at a pressure slightly higher than the supply pressure.

[0107] Exemplarily, cleaning water is intermittently supplied to the filter debris nozzle at intervals of about 1 second. That is, the cleaning water valve is opened for 1 second to supply cleaning water, and then closed for 1 second to stop the supply of cleaning water. This process is repeated. Such a process of intermittently supplying cleaning water is called "interval cleaning". Preferably, the interval cleaning lasts for 16s to 32s; in this embodiment, it is set to control the cleaning water valve to be intermittently opened and closed for 1s respectively, and the interval cleaning execution time is 20s, that is, the opening and closing of the clean water valve is repeated 10 times. The above-mentioned interval cleaning can exert an impact force on the fiber debris that is tightly attached to the outer rear wall of the inner cylinder and the inner rear wall of the outer cylinder, so that the fiber debris has fluidity.

[0108] In addition, when the cleaning water valve is opened for the first time, the fan starts and the suction force of the fan is used to clean the fiber debris on the surface of the fan blades and the air duct.

[0109] After that, after the interval cleaning of the cleaning water is completed, the cleaning water valve is opened for a predetermined time, so that the cleaning water is continuously supplied. At this time, the time for continuously supplying the cleaning water is about 5s to 20s. Here, the process of continuously supplying the cleaning water is referred to as "continuous cleaning". In this embodiment, the continuous cleaning execution time is 10s, so as to thoroughly clean the outer rear wall of the inner drum and the inner rear wall of the outer drum. The above-mentioned continuous cleaning can separate the fluid fiber scraps from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0110] When the cleaning water valve is opened for continuous cleaning, the inner drum maintains a rotation speed of 40-60rpm for forward and reverse rotation to drive the water to move, so that the directly impacted or splashed water can clean and cover the outer rear wall area of ​​the inner drum and the inner rear wall area of ​​the outer drum.

[0111] During the above cleaning process, the drain pump does not operate, that is, remains in a closed state.

[0112] As needed, repeat the above cylinder cleaning procedure 2 or 3 times.

[0113] After cleaning, the fan continues to work for a certain period of time, and at the same time, the heater is turned on to heat and evaporate the remaining moisture in the air duct to keep the drying air duct free of water and avoid corrosion to the drying air duct.

[0114] Preferably, the above cleaning procedure is not carried out simultaneously with the supply of rinsing water or other water. That is, when the supply pressure of the cleaning water is lower than the normal pressure, if the supply of rinsing or other water and the supply of cleaning water are carried out simultaneously, the pressure of the cleaning water supplied will become lower.

[0115] The time and number of times the cleaning water valve is opened and closed during the above interval cleaning, as well as the time and number of times continuous cleaning is performed, can be customized and selected by the user according to needs to achieve a better cleaning effect.

[0116] When the user chooses to execute the drying program alone, the drum cleaning program is executed before the drying program starts. The cleaning water valve is opened and closed intermittently, so that the cleaning water is intermittently supplied to the cleaning water inlet column, and the cleaning water is sprayed between the inner drum and the outer drum through the debris nozzle. The cleaning water valve is intermittently supplied for a certain period of time, and then the cleaning water valve is continuously opened for continuous cleaning for a certain period of time.

[0117] Here, the reason why the washing water is intermittently supplied is that when the pressure of the supplied washing water is low, the spray pressure of the washing water can be temporarily increased in the case of intermittent supply of the washing water compared to the case of continuous supply of the washing water. That is, by closing the washing water valve, the pressure of the washing water controlled by the washing water valve can be temporarily increased, and as the washing water with increased pressure is intermittently supplied, the washing water supplied from the condensed water supply device is sprayed at a pressure slightly higher than the supply pressure.

[0118] Exemplarily, cleaning water is intermittently supplied to the filter debris nozzle at intervals of about 1 second. That is, the cleaning water valve is opened for 1 second to supply cleaning water, and then closed for 1 second to stop the supply of cleaning water. This process is repeated. Such a process of intermittently supplying cleaning water is called "interval cleaning". Preferably, the interval cleaning lasts for 16s to 32s; in this embodiment, it is set to control the cleaning water valve to be intermittently opened and closed for 1s respectively, and the interval cleaning execution time is 20s, that is, the opening and closing of the clean water valve is repeated 10 times. The above-mentioned interval cleaning can exert an impact force on the fiber debris that is tightly attached to the outer rear wall of the inner cylinder and the inner rear wall of the outer cylinder, so that the fiber debris has fluidity.

[0119] In addition, when the cleaning water valve is opened for the first time, the fan starts and the suction force of the fan is used to clean the fiber debris on the surface of the fan blades and the air duct.

[0120] After that, after the interval cleaning of the cleaning water is completed, the cleaning water valve is opened for a predetermined time, so that the cleaning water is continuously supplied. At this time, the time for continuously supplying the cleaning water is about 5s to 20s. Here, the process of continuously supplying the cleaning water is referred to as "continuous cleaning". In this embodiment, the continuous cleaning execution time is 10s, so as to thoroughly clean the outer rear wall of the inner drum and the inner rear wall of the outer drum. The above-mentioned continuous cleaning can separate the fluid fiber scraps from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0121] When the cleaning water valve is opened for continuous cleaning, the inner drum maintains a rotation speed of 40-60rpm for forward and reverse rotation to drive the water to move, so that the directly impacted or splashed water can clean and cover the outer rear wall area of ​​the inner drum and the inner rear wall area of ​​the outer drum.

[0122] During the drum cleaning and drying procedures, the drainage pump remains open for 15 to 25 seconds within the second minute to drain water and discharge the cleaned fiber scraps and the like separated from the outer rear wall of the inner drum and the inner rear wall of the outer drum.

[0123] As needed, repeat the above cylinder cleaning procedure 2 or 3 times.

[0124] After cleaning, the fan continues to work for a certain period of time, and at the same time, the heater is turned on to heat and evaporate the remaining moisture in the air duct to keep the drying air duct free of water and avoid corrosion to the drying air duct.

[0125] Preferably, the above cleaning procedure is not carried out simultaneously with the supply of rinsing water or other water. That is, when the supply pressure of the cleaning water is lower than the normal pressure, if the supply of rinsing or other water and the supply of cleaning water are carried out simultaneously, the pressure of the cleaning water supplied will become lower.

[0126] The time and number of times the cleaning water valve is opened and closed during the above interval cleaning, as well as the time and number of times continuous cleaning is performed, can be customized and selected by the user according to needs to achieve a better cleaning effect.

[0127] The present invention provides a method for cleaning the drum of a washing machine, which can remove fiber scraps and the like remaining between an inner drum and an outer drum to prevent the fiber scraps and the like from easily entering the gap, thereby maintaining the continuous good performance of the washing machine; and effectively prevent the breeding of details and improve the user experience.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
